Hi I was wondering how you calculate the NPV, Units Sold, and Salvage Value?

valuating Risk: Sensitivity Analysis -eusitivity of NPV and to Variations in Input Variables Perform a sensitivity analysis on the unit sales, salvage value, and cost of capital for the project. Assume that each of these variables can vary from its base-case, or expected, value by plus and minus 10%, 20%, and 30%. Include a sensitivity diagram and use excel "data tables". 6 Deviation from Base Case
